Question

3m - 4n=1
3m - 2n=-1
without solving witch method you would use to solve each system; graphing,substitution, or elimination

Answer 1

can anyone help?

Answer 2

Do you know how to use each of those methods?
Besides graphing...pretty self explanatory and cumbersome

Answer 3

I know how to use the elimination method

Answer 4

that's about it but I wanna make sure I pick the right one

Answer 5

Well...that would help a lot with this problem if you catch my drift (๑•́ ₃ •̀๑)

Answer 6

lol so its ok if I use the elimination?

Answer 7

3m - 4n= 1
3m - 2n=-1

Basically...you want to subtract the 2 equations right on top of 1 another or addition in other cases (w/e) it takes to get rid of 1 of the variables

Answer 8

3m-3m=0
-4n-(-2n)=-2n
1-(-1)=2

-2n=2

n=-1

Answer 9

then you plug in n into 1 of the equations to solve for m

Answer 10

Technically, you could also sub, but elimination would be faster in this case

Answer 11

okay thank you for the help means a lot @porkbuns
